Abstract

Biodiversity indices and abundance of demersal resources in Hormozgan waters (53 00E to 57 00E) was studied by Bottom trawl survey during winter season, 2013. Sampling was done by R/V Ferdos 1. In this study, 89 stations within the 10-20 m, 20-30 m and 30-50 m depth layers were sampled and abundance and Species diversity of demersal fish communities at different depths were evaluated using various indices. In this study 99 taxa communities were identified including 88 fish species and 13 species or species groups that belonged to the other marine organisms such as crabs, sea cucumbers, sea snakes, jelly fish and corals. The value for the Shannon (H́ ) index for the entire investigated area (10-50 m depths) were 3. 21, Simpson (D), 0. 06, Pielou (J), 0. 69, Margalef (R), 7. 55 and Menhinick (IMen), were 0. 16. The value indices in different depths of 10-20 m, 20-30 m and 30-50 m were identical. Based on the results of Shannon and Simpson indices, this area has a fair quality of population in number of species, however species richness indices indicated low species richness and due to high water temperature and salinity degree, this area is under stress.
